UPDATE: We've been contacted by multiple readers who say that the aforementioned blank screen issue can be corrected by changing up TV settings. You can also start the console in Safe Mode and change HDCP 2.2 to HDCP 1.4, and both 4K and HDR will apparently work afterwards.

What does a console have to do among all else? Display a picture, of course. And the main reason to get a PS4 Pro is to play games in 4K UHD with brilliant HDR gamuts. It seems that Sony's new Polaris-enabled PS4 Pro is having a problem with this basic feature, which happens to be the console's main selling point.

According to Forbes, many PS4 Pro users are reporting blank screens while trying to game in 4K, with the new system marking their 4K UHDTV's as incapable of displaying 3840 × 2160 images.

The issues seem to stem from the PS4 Pro's firmware itself, but Sony is apparently blaming TV companies, and TV companies turn around and blame Sony. No one has admitted fault just yet, but the consensus is that the PS4 Pro's games, rather than the console itself, determines how the HDR spec is utilized.

"First, if I connect the console directly to my TV and check the console's Video Output Information before firing up an HDR game, the console informs me that my TV can handle RGB HDR at 2K or 4K resolution. However, if actually start playing an HDR game, which automatically makes my TV switch into HDR mode, the HDR output changes. With Deus Ex: Mankind Divided it changes to YUV420, while with Uncharted 4 it changes to YUV422.

"This suggests that the exact specifications of the HDR your console is outputting are actually determined by the particular game, rather than just the console's hardware.

"If I loop the PS4 Pro through a Samsung K950 Dolby Atmos sound bar I'm currently testing, then the HDR output always reads YUV420. I couldn't find any way to reproduce the RGB output reading before starting an HDR game that I get if I connect the PS4 Pro directly to the TV. Yet the K950 sound bar passes through RGB HDR from Samsung's K8500 Ultra HD Blu-ray player without any problems."

Gamers and sources also guess that there's a failed HDCP 2.2 handshake going on somewhere between the console and the TV.

"According to various forum posts, it looks like the issue is the HDCP handshake, with different games using different colour spaces for HDR, and that could be a major problem. If the system isn't outputting a single unified format, it could be that some components in people's AV chains are not passing through the signal the same based on their TV, AV receiver or the game they're playing.

"One fix was suggested to boot PS4 Pro into Safe Mode, and changing the HDCP from 2.2 to 1.4, but this could only lead to further incompatibility issues in some scenarios while fixing others."

Whatever the culprit may be, Sony needs to ensure this gets fixed ASAP especially with Black Friday rolling around. People are eyeing 4K UHDTVs like crazy right now, and nothing's worse than thinking you spent your hard-earned money on a lemon TV.

Considering 4K and HDR are the main reasons to even buy a PS4 Pro, this malfunction could harm Sony in the long run, especially with many critics seeing the system as a blatant cash-grab.

Make sure you hold off on buying a PS4 Pro until this problem gets fixed.
